Recently, I've seen a bunch of people discussing block builders and bundles. The more I look at it, the more it resembles the "mysterious channels" research from back in the day. In fact, retail investors just need to know enough: don't fantasize about every trade executing exactly at the price on your screen. On-chain, someone can bundle your intentions, cut in line, or change the order. Just remember, "placing an order = exposing myself," and that's enough. My approach is pretty simple: split large orders into smaller ones, don't chase after every tiny fluctuation, better to eat a little less than to risk becoming a lesson for others. Recently, the debate over privacy coins/mixing and their compliance boundaries has been quite intense and divisive. But for someone like me who just wants to trade properly, the most practical thing is: the more convoluted and "mysterious" the path, the less you can tell who might have betrayed you if something goes wrong... Anyway, I just want to stay alive.
